Question

बेंजल्डिहाइड से बेंजोइक अम्ल तैयार करें।
Prepare benzoic acid from benzaldehyde.​

Answer 1

Answer:

Explanation:

by using alkaline KMnO₄

Answer 2

The reaction is started by converting benzoic acid to benzoyl chloride with the help of phosphorus pentachloride. A chlorination reaction occurs when this reagent changes an acidic group to a chloride group. As a result, the reaction is as follows:

Now, because the -Cl group is a better leaving group, it may easily undergo a reduction process in the presence of Lindlar's catalyst, which is composed of H2/Pd,BaSO4.

The alternative way for this reaction can be done by slightly altering the reaction conditions, such as using thionyl chloride instead of phosphorus pentachloride and replacing Lindlar's catalyst with LiAlH4 followed by PCC or PDC, and do not be confused when such questions are posed.
